3.1.B.B1:Explain that the information passed from parents to offspring is transmitted by means of genes which are coded in DNA molecules.
Explain the basic process of DNA replication.
Describe the basic processes of transcription and translation.
Explain how crossing over, jumping genes, and deletion and duplication of genes results in genetic variation.
Explain how mutations can alter genetic information and the possible consequences on resultant cells.
3.1.B.B2:Describe how the process of meiosis results in the formation of haploid gametes and analyze the importance of meiosis in sexual reproduction.
\Compare and contrast the function of mitosis and meiosis.
\Illustrate that the sorting and recombining of genes in sexual reproduction results in a great variety of possible gene combinations in offspring. 3.1.B.B3:Describe the basic structure of DNA, including the role of hydrogen bonding.
Explain how the process of DNA replication results in the transmission and conservation of the genetic code.
Describe how transcription and translation result in gene expression.
Differentiate among the end products of replication, transcription, and translation.
Cite evidence to support that the genetic code is universal.
3.1.B.B4:Explain how genetic technologies have impacted the fields of medicine, forensics, and agriculture
3.1.B.B5:PATTERNS
Describe how Mendel’s laws of segregation and independent assortment can be observed through patterns of inheritance.
Distinguish among observed inheritance patterns caused by several types of genetic traits (dominant, recessive, codominant, sex-linked, polygenic, incomplete dominance, multiple alleles) CONSTANCY AND CHANGE
Explain how the processes of replication, transcription, and translation are similar in all organisms. Explain how gene actions, patterns of heredity, and reproduction of cells and organisms account for the continuity of life. SCALE
Demonstrate how inherited characteristics can be observed at the molecular, cellular, and organism levels. 3.1.B.B6:
Compare and contrast scientific theories.
Know that both direct and indirect observations are used by scientists to study the natural world and universe.
Identify questions and concepts that guide scientific investigations.
Formulate and revise explanations and models using logic and evidence.
Recognize and analyze alternative explanations and models.
Explain the importance of accuracy and precision in making valid measurements.
Examine the status of existing theories.
Evaluate experimental information for relevance and adherence to science processes.
Judge that conclusions are consistent and logical with experimental conditions.
Interpret results of experimental research to predict new information, propose additional investigable questions, or advance a solution.
1. Do you think obesity is genetic? Why or why not?
2. Look at your family history. Do you feel you body shape and genetic make-up is similar or different than other family members?
3. Do you think gender makes a difference in your body shape? Do you think gender makes a difference in your body image? Explain.
4. Can diet and exercise alter genetic obesity? Why or why not?
